[arin-ppml] Policy Proposal: Equitable Distribution of IPv4 Resources before IPv4 Run out

I support the idea of trying to equalize the last bit of
IPv4 address distribution, which this proposal is trying
to address.

However, I think that while the moral is a Good Thing, there
is no practical way to mandate it.

If this proposal were to be supported I would ask that the
author modify it so that at the least, there would be an
automatic expiration to this.

The cold hard fact of the matter is that ANY isp or other 
"small or Very Small" organization that is NOT requesting
IP addressing at this time to meet their projected future
needs, is likely to get shafted when IPv4 runs out.

On the day of IPv4 runout, if an ISP or organization does
not have a supply of IPv4 to carry them forward for the
immediate future, due to lack of planning, then I daresay
they DESERVE to go bankrupt.

Do we really want network administrators who aren't paying
attention to the gas guage to be driving the Internet into
the future?

> Policy Proposal Name: Equitable Distribution of IPv4 
> Resources before IPv4 Run out
> Author: Michael K. Smith
> Proposal Version: 1
> Submission Date: 05/20/2008
> Proposal type: new
> Policy term: permanent
> Policy statement:
> Upon receipt of the last allocation of IPv4 address space to 
> ARIN from IANA, ARIN will reserve address space within the 
> allocated block for Organizations within the defined ARIN 
> Organizational Size determinations (Extra Small, Small, 
> Large, Extra Large) based upon the utilization percentages 
> for each group gathered from the statistics of the last two 
> IANA allocations to ARIN.  In order to make the allocation 
> percentages mathematically feasible, the percentages will be 
> rounded to the closest whole number and, subsequently, the 
> the closest bit boundary for assignment the maximum 
> allocation size for the Organization size as defined by ARIN.
> Once the final IANA allocation is received, ARIN will publish 
> the allocation percentages that will be used for the final 
> allocation to the PPML and ARIN website with the necessary 
> documentation supporting the assignment of percentages.
> Rationale:
> Description:
> This policy is designed to allow Organizations of the various 
> defined sizes to continue to receive address allocations from 
> the last available space and is slanted towards ensuring that 
> organizations within the Large, Small and Extra Small groups 
> (and more specifically, the Small and Extra Small groups) are 
> able to get additional IPv4 space at the end of the ARIN's 
> ability to allocate such space.  Given the statistics below, 
> it is likely that Extra Large Organizations would get most or 
> all of the last remaining space because given the amount they 
> have been allocated to date.  This policy would help ensure 
> that other Organizations had a statistically equal 
> opportunity to receive space as well.
> Example:
> Please see http://www.arin.net/statistics/index.html (Note: 
> the statistics are generated from IP allocations from 2006 
> and 2007).  This policy would require statistics to be 
> limited to the previous 2 IANA allocations to ARIN.)
> The present distribution as of May 20th 2008 is:
> Extra Large: 83.11%
> Large: 6.75%
> Small: 9.00%
> Extra Small: 1.14%
> With this example, ARIN would reserve address space in the 
> final IANA allocation according to those percentages, to the 
> extent that it is mathematically possible within the existing 
> range. In order to make the math work, rounding would give us:
> Extra Large: 83%
> Large: 7%
> Small: 9%
> Extra Small: 1%
> Who is affected:
> All ARIN Members will be affected by this policy.  I assume 
> that smaller providers will benefit from having some space 
> available to them beyond where they would be with an organic 
> allocation model, and the Extra Large Organizations would 
> experience some pain because, using the model above, they 
> would be excluded from being allocated 17% of the remaining 
> space, even if they had all of the necessary justifications 
> for receiving allocations from within that space.
> Policy Enforcement:
> ARIN staff will have to enforce this policy and ensure that 
> allocations stay within the published percentages.
> Financial and Liability Implications:
> Financially, there may be additional resources required by 
> ARIN Staff to allocate resources using this model.  These 
> resources might include application development, staff 
> training and tracking of allocations based upon the model.
> ARIN may have legal liability should Organizations that were 
> denied space according to the model decide to contest the 
> legality of the policy in court.
> Timetable for implementation:  Upon receipt of finall IANA 
> allocation (roughly 2011).
